One of my great joys on visiting Berkeley was to meet Bret Victor, of Magic Ink fame. I mentioned to him that I had been working with a student on a visual lambda calculus, in part because I wanted a way to explain lambda calculus to my eight-year old daughter and son. He responded with a game involving alligators and their eggs, such a clever morphing of lambda calculus that it wasn't until I reached the end that I realized exactly what was going on.
So far, I've had a chance to show it to my daughter, who managed to successfully solve the problem at the end. She guessed a definition of 'not', and then applied 'not' to 'true' and checked that the result is 'false'. But she was most interested in drawing pictures of alligators! I expect it would be more fun to use if there was software that implemented the game.
